    How do I replace a 1996 Jeep radio with a Pioneer radio by matching the wires manually?

    It should be red to green, orange to purple, maroon to turquoise, pink to silver, and clear to black.
  • Question
    How do I connect the stereo to the equalizer if the stereo has no input port?
    Community Answer
    You have to buy an adapter cable. If you buy from a store like Radio Shack, you may be able to get the salesman to come outside and help you install it... For free!
  • Question
    If I have an aftermarket Pioneer radio, and want to replace it with another Pioneer radio, do I need a new wiring harness?
    Community Answer
    Not necessarily, just compare the harnesses and once they match, you can go ahead.
  • Question
    Can the radio short out my battery?
    Community Answer
    The radio can drain the battery, but should not short it out.
  • Question
    Where can I connect an amp remote if a stereo does not have a remote on cable?
    Community Answer
    Use the factory fuse box. Find a wire that turns on/off with the ignition key.
  • Question
    What do I do if the stereo won't work after I disconnected it and put it back together?
    Community Answer
    Check your connections. Make sure you have 12 volts to hot wire and a good ground. Some head units have a separate wire that must go to voltage for the display separately.
  • Question
    What's the difference between an amp and a booster?
    Community Answer
    Some people consider them the same. However, I would say that a booster is a 'go between' only to increase the power input to a subwoofer (or set of subwoofers), whereas an amplifier is to increase the power to all channels. Some amps also will provide an exclusive (or dedicated) output for a subwoofer or set of subwoofers in addition to the RF RR LF LR 4 channels.
  • Question
    I have a second hand Peugeot 307 with a hole in the dashboard where a radio used to be. Is it a simple case of plugging in some connectors to a new radio unit?
    Community Answer
    This will work only if you replace with a stereo with same connectors.
  • Question
    Do I have to unhook the battery?
    Community Answer
    No, but it doesn't hurt as a good safety precaution to prevent electric shock.
  • Question
    Can I get an adapter for a car stereo if the connectors are different?
    Community Answer
    Very often, yes. Retailer sites like Crutchfield and Amazon will show you what's needed to connect a radio you bought there to different makes and models of car. They're usually not strictly necessary but can simplify the installation.
